BD Diesel continues their prolific output with their new Dana 70 differential cover. Most differential covers are big and bulky and fling lubricating oil off the ring gear. The Dana 70 design deflects the oil back onto the ring gear and into the pinion gear to give it cooler, longer life. It’s also designed with an extra sump at the bottom for the gears to pick up oil. Other features include internal and external cooling fins, stainless steel Allen head cap bolts, fill plug, a magnetic drain plug, and a gasket-less cover that has an integral reusable Viton O-ring.
